Moving foul pipe

[Funkyboy]

Hi all,

I would like a exstension along the back of my house. Right in the the middle of the back wall is a foul pipe with a pipe branching into it from my bathroom.
I don't want a column with the foul pipe encased in it n the new kitchen dinner. Are there any other alternatives? Also is there any building regulations around foul pipes?

Thanks

Any outlet from bathroom WC will be above floor level. Even with flat roof extension, this means foul pipe can be extended in roof space. Location of manholes/diversion etc. all need taking into account and roof timbers designed to suit.

Do building regs allow foul pipe to be extended in roof space? Also how would you get access if needed? It will be a single level exstension with a pitched roof under upstairs windows
Thanks

Provided pipe run is straight within roof space, access for rodding can be achieved externally. This is where you need to engage plumber to joint and support pipe correctly.

Is it a single story extension or double?
I would dog leg it to the side of the house and use manhole for change of direction to get you back into your drainage line. If levels etc permits.

As you can go under the extension as long as you have an access point to rod, but we all ways try to move the drainage outside the building footprint, just to be safe. From a builders opinion, I'm not a plumber yet....
